Title: Improvements in typographic machines
IPC: B41B7/00
Filed: 1919-10-17
Abstract: 156,350. Druitt, P. W., and Gilpin, W. H. Oct. 17, 1919. Single-type composing and casting machines ; matrices.-In machines such as described in Specifications 1903/00 and 11870/13 in which the matrices of a justified line are separated and presented singly to the mould, means is provided for casting from matrices having more than one character. The presentation-plunger a, which clamps the matrices against the mould, has a vertically sliding head a<1> which may engage a fixed aligning-stopc<0> on the mould or may be supported at a higher level, when the lower characters of the matrices are to be used, by means of an aligning-bar b mounted to slide on the plunger. When the upper character of a matrix is to be cast from, the bar b is retracted and the head a<1> is depressed on to the stop c‹ by a lever f and a spring-pressed plunger f<2> carried by a vertically moving slide i. The head a' is raised, as the plunger a retires, by a stop g which engages an incline f<1> on the lever f. The change in position of the bar b is effected by a cam h carried by the plunger a and adapted to be rotated by a ratchet wheel h<1> and a pawl i<o> carried bv the slide i. When the slide i reciprocates the plunger is normally in the advanced position so that the ratchet-wheel is not engaged by the pawl. When a change of fount is required, a special controller-matrix is inserted in the matrix line whereby the plunger a is prevented from advancing and the bar b is shifted by the ratchetmechanism.

Title: Improvements in or relating to chucks
IPC: B23B31/175
Filed: 1954-09-02
Abstract: 787,580. Chucks; face-plates. BURNERD & CO., Ltd., F. (Gamet, L.). Sept. 1, 1955 [Sept. 2, 1954], No. 25541/54. Class 83 (3). A chuck in which jaw-carriers 6, in radial channels 5, are operated by eccentrics 8 rotated by levers 8a, comprises cavities 7, in the carriers, presenting opposite faces 7a, 7b against which the eccentrics bear, and shafts 9 supporting the eccentrics and journalled in the body of the chuck which has an axial-bore accommodating a member 13 operating the levels. The channels 5 are of T-section, and similar channels 20 are formed in the carriers to receive blocks 21 to which the jaws 22 are fixed by screws 24. The jaws, of tempered steel when gripping- teeth are provided, and of non-tempered steel when they conform to the shape of the work and have no teeth, bear against serrations on the front face of the carriers. A draw-bar 14 is connected by nuts 15-17 to the operating- member 13, which receives the ends of the levers in recesses 13a and is guided by a pin 18 riding in a slot 19 in the bore of the chuck. A dividedring 29a, 29b, in a groove in the bore of the chuck and the jaw-carriers 6, seals against the escape of lubricant from the interior of the chuck, the eccentrics being lubricated from the exterior of the chuck through passages 10 in their shafts 9. The front face of the jawcarriers is set back from the front face of the chuck in order that the latter may be used as a face-plate after removal of the jaws, radial grooves 26 and holes 28 being formed in the face of the chuck between the jaw-carriers to facilitate the clamping of work. Friction between the eccentric 8 and the faces 7a, 7b prevents the eccentric from sliding and releasing the clamping-pressure if the force on the draw-bar is released. In a modification, the member 13 may be operated by a nut 42, Fig. 5, or a screw rotated by bevel-gearing 44,45.

Filed: 1937-09-21
Abstract: 498,179. Type - making machines ; pumps. GEE & CO. (PUBLISHERS), Ltd., and GUNN, A. G. Sept. 21, 1937, No. 25643. [Class 100 (iii)] [Also in Group XXVIII] Metal pumps.-To enable casting-metal at a lower temperature than usual to be used, so that the time required for the setting of the metal in the mould is reduced, an adjustable control of the amount of metal admitted to the pump-well is effected on the delivery or pressure side of the piston without being dependent on the position thereof. The drawback of metal from the pump-nozzle can thereby be increased, so that chilling of the metal in the nozzle is avoided. The inlet-passage 13, Fig. 1, for the metal may be formed in the bottom of the pump-barrel 1, and is controlled by a valve 14, which is adjusted by means of a lever 20 and a screw 26. The known float-valve 15, which seats itself during the rise of the piston and restricts the drawback, is provided with grooves 18, Fig. 2, of such a size as to permit a substantial withdrawal of metal therethrough, and has a conical projection 16, which, during the downstroke of the piston, fits into a recess at the end of the inlet-passage 13 and closes it. The valve also acts as a distance-piece to limit the rise of the projection 16 from its seating. By adjustment of the valve 14, the drawback can be regulated so that the metal in the nozzle is withdrawn to about the general level of the metal in the pot.
